Alarm Contacts (Plug-In Terminal Block)
Normally open (NO) and normally closed (NC) alarm contacts are provided on the rear panel of the TRACER 5045 system. In normal operation, the NC contact is electrically connected to the common contact (COM) and the NO contact is isolated. During an alarm condition, the NC contact becomes isolated and the NO is electrically connected to COM. This allows alarm conditions to be reported to external alarm monitoring systems.
